Type Alias SDL_AppQuit_func 

pub type SDL_AppQuit_func = Option<unsafe extern "C" fn(appstate: *mut c_void, result: SDL_AppResult)>;

Function pointer typedef for SDL_AppQuit.

These are used by SDL_EnterAppMainCallbacks. This mechanism operates behind the scenes for apps using the optional main callbacks. Apps that want to use this should just implement SDL_AppEvent directly.

Parameter: appstate an optional pointer, provided by the app in SDL_AppInit. Parameter: result the result code that terminated the app (success or failure).

Available Since: This datatype is available since SDL 3.2.0.
